("Westmount" or the "Company")

Commencement of drilling operations at Sapote-1, Canje Block, offshore Guyana

Westmount Energy Limited (UK AIM: WTE.L, USA OTCQB: WMELF) is pleased to note the announcement by the Maritime Administration Department, Guyana, dated 25th August 2021, that the Stena DrillMAX drillship will commence drilling operations at the Sapote-1 wellsite on the Canje Block, offshore Guyana, on 28th August 2021.

As previously announced, Westmount holds an indirect interest in the Canje Block as a result of its circa 7.2% interest in the issued share capital of JHI Associates Inc. ("JHI")1. The Canje Block is currently operated by an ExxonMobil subsidiary, Esso Exploration & Production Guyana Limited (35%), with TotalEnergies E&P Guyana B.V. (35%), JHI Associates (BVI) Inc. (17.5%) and Mid-Atlantic Oil & Gas Inc. (12.5%) as partners.

Sapote-1 is located in the southeast of the Canje Block, approximately 60kms north of the Campanian and Santonian Maka Central-1 stacked pay discovery, in a new depositional setting linked to the Berbice canyon system. Sapote-1 is an independent multi-layer prospect, which will evaluate several Upper Cretaceous targets, and is potentially the largest prospect drilled on the Canje block to date. Drilling of Sapote-1 is anticipated to take 60 days, with results anticipated in late October.

Following a 2018 farm-out to Total and subsequent transactions, JHI is funded for the 2021 Canje drilling campaign, including the Sapote-1 well, and multiple additional wells.
